I would be willing to bet that star ratings are directly proportional to the IQs of the reviewers in this one. If you have the brain power to keep up with the plot yet still be able to consider its deeper implications, you'll find this to be one of the most intellecually powerful action films to date. And if you consider the ideas that this film imbeds in our own minds, you nearly have to be in a dream-like state yourself to grasp it all. I still can't decide which was more interesting: the movie itself, or the conversation it evoked between my wife and me on the way home. Four thumbs up.
